` To all 'whom t may concern.'

Be it known that I, JOHN RUST, a: citizen of the United States, residing at lthe .city and county of Kalamazoo, State of M1ch1- gan, have invented certain new and useful Improvements in Adjustable Beds, of which the following is a specification.

This invention relates to improvements in adjustable beds.

The main objects of this invention are:

First, to provide an improved adjustable bed well adapted for the use of invalids and in hospitals.

Second, to provide an improved adjustable bed which may be tilted as a whole to elevate the head or the foot or adjusted to provide a seat or chair.

Third, to provide an improved bed having these advanta es which is very easily manipulated to different-positions.

Fourth, to provide an 'improved adjustable bed which is comparatively simple and` economical in structure. Further objects, structural details,

I accomplish the objects of my invention by the devices and means described in the following specication. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in whlch:

Figure I is a plan viewof a structure embodym the features of my invention, portions o? the bed bottom being omitted.

Fig. II is a perspective view.

In the drawing similar reference characparts lthroughout the several views, and the sectional views are taken looking in the direction of the little arrows'atjthe ends of the section lines.

Referring to the drawing, the structure illustrated comprises a bed frame, designated generally-b the numeral-1, and comprising head an foot members and side rails 2. The bed bottom comprises the head section 3, seat section 4 and -foot section 5.

These sections areform'ed of side pieces conby suitable cross pieces, the intermediate cross pieces 6 being shaped like inverted yokes.

The iiexible spring bottom 7 is continuous, only a portion, however, being illustrated. f

On each side rail I mount a hanger 8 having bearings 9, at the lower ends thereof for the actuatmg shaft 10. Segments 11 are rigidlysecured to the head section 3 at the inner end thereof. The shaft 10 is provided with pinions 12 meshing with these seg- The segments are pivotally supported by thepivots 13 carried by the hangers,-see Fig. VI.

The shaft is provided with a locking ratchet wheel 14. A locking pawl 15 provided with a series the ratchet wheel is hangers at 16l v To retain the locking pawl in engaging position it is provided with a reciprocating catch 18 adaptedtoengage a pin 19 on the hanger,-see Fig. VII. To release the pawl this catch 18 is retracted, it being provided with a finger -piece 20 for convenience in manipulation. With this catch retracted the pawl may be lifted from or is free to ratchet over the wheel 14.

The bed bottom sectionsfare joined by the hinges 21. I

The foot section 5 has downwardly projecting arms 22 at its inner end which are connected to the segments by the links v23 so that when the segments are swung by means of the actuating shaft lthe `foot section is swung on its pivot.

of teeth 17 to coact with To support pair of rests 24 adapted to engage key hole slots 25 in the siderails. These rests are disposed so that they support .the end ofthe seat vportion adjacent the. foot section,- see Fig. III.

To limit the swing of the end section rela- "tive to the seat section II provide links 26 which are pivoted tothe seat-section at 27 and longitudinally slotted-ata28 lto engage:

- clined position, that is, with the head elcvated, as shown inFig. V, or to avrearwardly inclined position or with the foot glue gated, as shown in Fig. IV, or as a seat, 25'

aslwni'n Fig. III, merely by the manipulation of the crank and the insertionor-removal of the supports or rests 24. These rests should be inserted when the bed is to` be adjusted as a seat and should be removed when the bed is to betilted to a forwardly inclined position, as shown in Fig. V.

My improved adjustable bed is very easily manipulated or adjusted by the means illustrated and may be securely locked in its adjusted positions.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In an adjustable bed, the combination.

of a frame comprising side rails, hangers on said side rails, a bed bottom comprising pivotally connected head, seat, and foot sections, segments on which said head section is mounted pivotally mounted on said hangers, a shaft carried by said hangers, pinions on said shaft coacting with said segments, depending arms on said foot section, links connecting said arms to said segments, links pivotally connected to said seat section and having a pin and slot connection with said 4 arms limiting the upward swing of said foot section relative to said seat section, and rests for said seat section removably mounted on saidside rails.

2. In an adjustable bed, the combination of a frame comprising side rails, hangers on j said side rails, a bed bottom comprising pivotally connected head, seat and foot sections, segments on which said head section is mounted pivotally mounted on said hangers, a shaft carried by said hangcis,apinions on said shaft coacting with said segments, depending arms on said foot section, links connecting said arms to said segments, and` links pivotally connected to said seat section vthe seat section when the structure is adjusted as a chair I provide a "depending arms on said foot section, connecting said arms to said segments, and

5. In an adjustable bed, the combination of a frame comprising side rails, hangers on said side rails, a bed bottom comprising pivotally connected head, seat and foot sections, segments on which said head section Iis mounted pivotally mounted on said hangers, a shaft carried by said hangers, pinions on said shaft coacting with said segments, a locking ratchet wheel on said shaft, a locking pawl coacting with said locking ratchet, illicxel ending arms on said foot section, and 6. In an adjustable bed, the combination of a supportin frame, a bed bottom com rising pivota y connected head, seat and' oot sections, the head section being supported for pivotal adjustment on said frame, segments secured to said head section, an actuating shaft, pinions on said shaft' coacting with said segments, a locking means for said shaft, links connecting said foot section to said segments, a locking means for `said shaft links connectingsaid foot section to said segments, links pivotally con-A nected to said seat Asection and having a lost connecting said arms to said segments.

7 In an adjustable bed, the combination of a supporting frame, a bed bottom comrising pivotally connected and adjustable ead, seat and foot sections, the head section being supported for ivotal adjustment on said frame and capa le of bein brought into alinement and tilted forward y or rearwardl'y, segments secured to said head section, an actuating shaft, pinions on said shaft coacting with said segments, a locking means for said shaft, links connecting said foot section to said segments, and rests for said seat section removably mounted on said side rails to support and limit the downward movement of the forward edge of said .seat when the .bed is adjusted as a chair.

8. In an adjustable bed, the combination of a supporting frame, a bed bottom comprisingvpivotally connected head, seat and foot sections, the head section being supported for pivotal adjustment on said frame, segments secured to said head section, an actuating shaft, pinions ,on said shaft co acting with said segments, a locking means for said shaft, links connecting said foot section to said segments, and links pivotally connected to said seat section and having a lost motion connection with said foot section limiting the upward swing thereof relative to said seat section.

9. In an adjustable bed, the combination of a supporting frame, a bed bottom comprising pivotally connected head, seat, and foot sections, the head section being supported for pivotal adjustment on said frame, adjusting members secured to said head section, links connecting said foot section to said adjusting members, and means limiting the upward swing of said foot section relative to said seat section so that after said .sections are brought into alinement continued actuation of the head section tilts the bed bottom as a whole.

In witness whereof, I have hereunto setmy hand and seal in the presence of two witnesses.
